* Fix a typo in the sql literal spec for grouped "and" equalityCourtland Caldwell2015-03-231-1/+1

* Delete should respect 'limit'Bradford Folkens2015-02-231-0/+8
| | | | | Conflicts: lib/arel/visitors/to_sql.rb
* Change the interface of `having` to match that of `where`Sean Griffin2015-01-274-13/+11
| | | | | | These two clauses have nearly identical semantics with regards to how they would be constructed as an AST. It doesn't make sense for their interfaces to be separate.
* Implement equality for `BindParam`Sean Griffin2015-01-251-0/+15
| | | | | It is impossible to test equality of things constructing trees with bind params otherwise.
* Allow a type caster to be given to the `Arel::Table` objectSean Griffin2014-12-291-0/+34
| | | | | | | | | This will allow most consuming code to avoid the deprecation introduced in 008445d6fd5f825d9b445ac75a7be67f0f7ab52c. The only code which will be affected is code that is building the `Arel::Table` object manually, rather than calling `arel_table` on an Active Record class. Hopefully this case will be rare enough that we don't need to introduce any additional APIs to work around it.
* Deprecate automatic type casting within ArelSean Griffin2014-12-261-0/+2
| | | | | | | | Rails now performs all casting eagerly, before passing the value into Arel. Once we remove this, the code on both sides will be simplified greatly. Ideally, we can provide the appropriate public APIs on the Rails side to ease this transition for library authors who depend on this behavior.
* Allow for handling quoted values in rangesSean Griffin2014-12-261-0/+47
| | | | | Since Active Record needs to eagerly cast values, we need to check for quoted infinity in our range handling
* {Matches,DoesNotMatch} support the ESCAPE clause with PostgreSQLKazuya NUMATA2014-12-251-0/+14
| | | | | to_SQL already has supported the ESCAPE clause in #318. PostgreSQL can use the ESCAPE clause too.
* Remove `engine` from `TreeManager` and subclassesSean Griffin2014-11-299-144/+133
| | | | | | This constructor parameter was unused for everything except the convenience methods `to_sql` and `where_sql`. We can pass the engine into those methods directly.
* Remove engine from the constructor arguments `Arel::Table`Sean Griffin2014-11-293-63/+28
| | | | | | | | | | | | | | | It is never used outside of convenience methods which are only used in tests. In practice, it just made constructing tables more complicated on the rails side. This is the minimum possible change to remove the constructor argument, but continue to have the tests passing. I'm not sure if we have a reason to keep `project` and friends, and the solution might actually just be to remove the engine from `SelectManager` and friends. As such I've held off on deleting those methods. We need to figure out what to do with `Table#from`. It's old invocation, which read `table.from(table)` was certainly nonsensical.
* Remove deprecated method "Table#primary_key"Sean Griffin2014-11-261-0/+19
| | | | | | | The only place this method was still used is on the MSSQL visitor. The visitor has all of the objects required to inline this lookup there. Since the `primary_key` method on the connection adapter will perform a query when called, we can cache the result on the visitor.
* remove extra space before 'ORDER BY'Nihad Abbasov2014-11-261-1/+8

* Support Oracle bind parameter valueYasuo Honda2014-11-201-1/+12
|
* Use class objects rather than strings for the dispatch cacheSean Griffin2014-11-181-1/+1
| | | | | | | | The only reason we're using strings is to pre-populate the cache, but `Class#name` returns a new string instance on every call. This is a pretty major source of memory usage. We don't technically need to pre-populate the cache, and not doing so allows us to go back to using cache objects
* Add order to BindParams in the ToSql collectorSean Griffin2014-11-176-10/+27
| | | | | | | | | | | | This removes the need for us to do the re-ordering by walking the AST in ActiveRecord. We're using a block to communicate with the collector, since the collector needs to be the thing which knows about the index, while the visitor is the thing that needs to know the syntax. The BindParam needs to know about neither of these things, so it's been changed to stop being a subclass of SqlLiteral I could also see an alternative implementation using format strings if for some reason blocks cause a problem.

* Deprecate passing ranges to `#in` and `#not_in`Sean Griffin2014-10-253-145/+143
| | | | | | | The goal of these methods should be to generate in nodes, not handle every possible permutation of more than one value. The `#between` and `#not_between` methods have been extracted, which better represent the semantics of handling ranges in SQL.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, doing ```ruby relation[:id].not_eq(4).and(relation[:id].not_in(1..3)) ``` will generate ```sql "id" != 4 AND "id" < 1 OR "id" > 3 ``` Which would incorrectly include records with an id of 4, as the OR statement has higher precidence than the AND statement. The `or` method on `Node` properly groups the statement in parenthesis.
